E030

Note: This check has been removed in Bootlint v1.x.

Found elements with a `.glyphicon-*` class that were missing the additional required `.glyphicon` class.

.glyphicon-* classes can't be used on their own; they must always also be accompanied by the .glyphicon class.

Wrong:

<span class="glyphicon-heart"></span>

Right:

<span class="glyphicon glyphicon-heart"></span>
